GENERAL DESCRIPTION
The AD8429 is an ultralow noise, instrumentation amplifier
designed for measuring extremely small signals over a wide
temperature range (40°C to +125°C).
The AD8429 excels at measuring tiny signals. It delivers ultralow
input noise performance of 1 nV/√Hz. The high CMRR of the
AD8429 prevents unwanted signals from corrupting the acqui-
sition. The CMRR increases as the gain increases, offering high
rejection when it is most needed. The high performance pin
configuration of the AD8429 allows it to reliably maintain high
CMRR at frequencies well beyond those of typical instrumentation
amplifiers.
The AD8429 reliably amplifies fast changing signals. Its current
feedback architecture provides high bandwidth at high gain, for
example, 1.2 MHz at G = 100. The design includes circuitry to im-
prove settling time after large input voltage transients. The AD8429
was designed for excellent distortion performance, allowing use in
demanding applications such as vibration analysis.
Gain is set from 1 to 10,000 with a single resistor. A reference
pin allows the user to offset the output voltage. This feature can
be useful to shift the output level when interfacing to a single
supply signal chain.
The AD8429 performance is specified over the extended industrial
temperature range of 40°C to +125°C. It is available in an 8-lead
plastic SOIC package.
